The cation exchange behaviour of hydrated ferric oxide, having reasonable chemical stability towards dilute acids, was studied. The preparative procedure, composition, chemical stability, thermogravimetric analysis, pH titrations, cation-exchange capacity and distribution coefficients (KD) of some metal ions in resin-aqueous solution systems are reported. In addition, some binary separations of cations have also been conducted on the basis of these KD values.
